/ Places in central Scotland to practice dry/mixed tooling?

I'm thinking of taking a pair of axes and some gear on a small trekking expedition to the north of Scotland next year. before I go, I thought I'd get some practice in but as I stay in Glasgow I was wondering if there was anywhere nearby to do so? I know the ice climbing wall at Braehead is now open but what about dry tooling/mixed venues or areas nearby?

Also, is there a general code of ethics on what constitutes a 'dry-tooling' climb when you aren't in a mountainous area? Don't confuse my tone, but I really don't fancy using public transport to travel the length of the country every week.

There's also this place that was being developed in Edinburgh not long ago: http://www.ukclimbing.com/forums/t.php?t=495862 (check the OP's links within that thread). Easy enough access from the west if that's the direction you'd be coming from.
